4 Claims. (Cl. 189-66) This invention relates to a reversible, pivotallymounted window with transversely shiftable pivot, and more particularlyto a windowwhich is so pivoted that. it may be swung through an angle ofthree hundred and sixty degrees, and to a method of operating same.

This application is a continuation-in-part of my copending application,Serial'No. 487,175, filed February 9, 1955, entitled Gyrating andSliding Pivot Window With Retractible Weather Bar. I

One of the principal objects of the invention is to provide a windowthat may be swung inside out, so that both sides may be cleaned from theinside of the building and still maintain anti-leakwise reveals, and inwhich the window requires no frame.

A further object of the invention is to provide a window in which thepivotal axis may be shifted withrespect to the sides of the grid of thefacade in which the window is mounted.

An additional object is to provide a window which may be repaired orcleaned on both sides without the use of scaffolding.

An additional object is to eliminate the necessity for a window frameand to close and/or seal the window against the grid of the facade of abuilding.

A still further object is to provide a shiftable pivot for a window,such that the pivot may be moved so that danger of striking partitionsor fins is avoided during swinging movement.

Yet another object is to provide a rectangular window that may berotated 180 or 360 through a rectangular opening which is smaller in onedimension than the corresponding dimension of the window.

These and other objects will appear hereinafter in the followingspecifications, which, taken with the accompanying drawings, constitutesa complete disclosure of the invention.

In the drawings:

Figure 1 is a horizontal section through my improved window just abovethe top edge of the lower sash rail;

Figure 2 is a view similar to Figure 1, showing the window shiftedslightly to the right and showing one movement of the pivot;

Figure 3 is a view similar to Figure 1, showing an additional shift ofthe pivot and the swinging or rotating of the window incounter-clockwise direction;

Figure 4 is a view similar to Figure 1, showing the window turned 180and in interfering position;

Figure 5 is a view similar to Figure 1, showing the window and its pivotshifted to the left to clear the fins;

Figure 6 is a view similar to Figure 1, showing in solid lines thewindow and its pivot swung to substantially closed position and indotted lines the window shifted to sealing position; and

Figure 7 is a fragmentary vertical section through my window showing theretractible sealing means at the head 2,744,593 Patented May 8, 1956figures, A represents an opening in the facade B of a building in whicha suitably glazed window sash 10 is are slidable in grooves 20 and 22for a purpose which will appear hereinafter.

The facade of the building includes. grid. elements 28 subdividing thebays thereof. Outside the grid members are the fins 30. My window isadapted to fit against the faces of the grid members and to rotate in anopening of less transverse width than that of the window sash.

Further, my window joins anti-leakwise reveals by engaging sealing means32, which may be suitable gasket material applied to gridmembers 28.

Further'to seal the sash, the sill and head are provided, respectively,with retractible bars 34 and 36 adapted to slide in slots 38 and 40,respectively. Bars 38 and 40 are provided with seals 42, which may besuitable gasket material applied to the bars. The bars may be moved toor from operative position either manually or by suitable mechanicalmeans. The means for retracting the bars is not a part of thisinvention.

This window is especially adapted for use in situations wherein thewindow of my aforementioned prior application will not operate. In someinstances, fins, mullions, partitions, or grid members will not permitthe sash to clear when operated as in my aforementioned priorapplication. To overcome these difliculties, the present device operatesin the manner now to be described.

Assuming that the window is in closed position as in Figures 1 and 7,with the sash rails 11 and 13 engaging seals 32 and with seals 42engaging bottom rail 15 and top rail 17, sealing bars 34 and 36 areretracted, into channels 38 and 40, respectively, to positions in whichthey will clear rails 15 and 17. The sash is then shifted to the rightas seen in Figure l to the position shown in Figure 2. Arms 12 and 16are then moved outwardly, and window 10 is rotated counter-clockwise, asshown in Figure 3, through an angle of The outward movement is on theorder of 25% to 30% the width of the window, so that the window rotatesin the grid opening.

Inward movement of arms 14 and 16 and sliding movement of window 10,with further inward swinging movement of arms 14 and 16, brings thewindow to the position shown in solid lines in Figure 6, and a slidingmovement to the dotted line portion of Figure 6 brings the rails 11 and13 into facewise engagement with seals 32. Bars 34 and 36 may now bereturned to normal position, as shown in Figure 7, engaging the faces ofrails 15 and 17. The window is now sealed to form anti-leakwise reveals,and, after cleaning, may either be left in this position or returned tothe position of Figure 1 by the operations just set forth.

The window of this invention requires no frame other than the gridmembers which comprise the facade of the building.

The above description and drawings disclose a single embodiment of theinvention, and specific language has been employed in describing theseveral figures. It will, nevertheless, be understood that nolimitations of the invention are thereby contemplated, and that variousalterations and modifications may be made such as would occur to oneskilled in the art to which the invention relates.

I claim:

1. A reversible window 'sash adapted to seal facewise against certain ofthe grid members composing the facade of a building and forming arectangular grid opening two opposite sides of which constitute windowjambs, one dimension of said grid opening being smaller than thecorresponding dimension of the window sash, comprising a pair of armslonger than half the window sash width at the head and stool of the gridopening, said arms each being pivoted at one end adjacent one gridmember, and having confronting grooves at their other ends, a windowsash having pivots midway of its width pivotally and slidably mounted insaid grooves, said grooves in normal position extending either side ofthe center line of the grid opening, whereby said window sash may beshifted in its plane to clear a grid member, then pivoted outwardly bymeans of the arms and rotated through an angle of one hundred eightydegrees in the opening.

2. A reversible window sash adapted to seal facewise against certain ofthe grid members composing the facade of a building which form arectangular grid opening two opposite sides of which constitute windowjambs, and in tions in facewise engagement with said grids in saidchannels, a pairof-arrns pivoted one at the head and the other at thestool adjacent one grid member and substantially longer than half thewidth of the grid opening, said arms having confronting grooves in theother ends thereof, said grooves in normal position extending eitherside of the center line of the grid opening, said window sash havingupper and lower pivots slidably and rotatably mounted in said grooves,whereby said window sash may be slid in its own plane to clear a gridmember, then moved outwardly on its arms and rotated through an angle ofone hundred eighty degrees in the grid opening, and then slid in itsplane and swung to closed position in facewise sealing engagement withthe grids, within the channels.

3. The window sash of claim 1, wherein retractible seals are provided atthe head and stool thereof.

4. The window sash of claim 2, wherein retractible seals are provided atthe head and stool thereof.
